L-Lysine (Essential Amino Acid Supplement)

CJ CheilJedang Corporation (Seoul South Korea; KRX: 097950; subsidiary of CJ Group); South Korean food and bio conglomerate; world's largest L-lysine producer (~25% global share) via fermentation biotechnology. Operates the world's first and only commercial-scale bio-based L-methionine facility at Kertih Biopolymer Park Terengganu Malaysia (80,000 MT/year; opened 2015 using genetically engineered E. coli K-12 fermenting plant sugars — producing L-methionine rather than racemic DL-methionine). CJ's fermentation-route L-methionine is chemically distinct from synthetic DL-methionine but is approved as nutritionally equivalent in poultry diets. Also produces tryptophan, threonine, and other feed amino acids globally. Pet food market interest in fermentation-derived (non-petrochemical) amino acids is growing.

CJ BIO, the bioscience division of CJ CheilJedang (Korea); world's largest single L-lysine producer by company; ~15-20% global lysine market share; operates the world's most efficient large-scale fermentation platform; produces from corn-based feedstock in Korea (HQ), Iowa USA, Shenyang China, Liaocheng China, Malaysia, Indonesia, and Brazil; invented high-yield lysine fermentation strains; also the global #1 in tryptophan and a top-5 threonine producer

World's largest MSG and amino acid producer AND sole-source supplier of ABF (Ajinomoto Build-up Film) — the insulating substrate used in advanced CPU/GPU packaging for all leading chips

Chinese fermentation company; the world's largest single L-Lysine HCl producer with a 300,000-tonne facility; headquartered in Langfang, Hebei province; exports L-Lysine HCl to over 90 countries; also produces threonine, glutamic acid, and other amino acids; part of the Chinese domestic amino acid export complex alongside Fufeng Group that supplies global swine and poultry feed industries

Blair Nebraska 280k MT; Castro Brazil 80k MT; Volgodonsk Russia 100k MT (sanctions risk post-2022); Biolys brand; petitioner in 2025 US anti-dumping case

Changchun Jilin; 480-500k MT capacity; largest vertically integrated corn biochemical manufacturer in Asia; 3M MT annual corn processing

800k+ MT total fermentation capacity; Yinchuan 210k MT + Chifeng 200k MT lysine; among China top 4 lysine producers

Decatur IL (340k MT) and Clinton IA (70k MT); ended dry lysine production 2021, shifted to liquid/encapsulated; petitioner in 2025 US anti-dumping case

China's largest fermentation-based amino acid company; operates one of the world's largest single biotechnology production complexes in Xinjiang, producing glutamic acid, lysine, xanthan gum, corn starch, and animal feed from corn wet milling at mega-scale; in 2022 attempted to purchase 300 acres near Grand Forks Air Force Base, North Dakota for a corn milling plant — blocked 5-0 by city council after Air Force cited national security risk (passive interception of sensitive drone communications); that failure highlighted how food ingredient producers can create intelligence collection infrastructure
